Makrolon® DQ5122 polycarbonate efficiently lights the way

The INNOVA series of luminaires from Trevos (opens in a new tab)operates in tough environments. The LED chips inside these luminaires are protected against dust, water and other elements by an optical light cover.This cover is one of the key elements that influence the light quality of the luminaire. Because of this, the material selected to form the light cover is equally important and must push the boundaries of existing solutions.

The INNOVA light cover has two very different primary optical functions. First, it needs to diffuse and guide the light that originates from the LED chips to provide a precise lighting geometry and avoid glare. Second, it must transmit as much light as possible to guarantee high lumen output per watt. The challenge lies in finding a way to meet both of these priorities. That’s where Makrolon® diffusion grades really shine.

Trevos’ use of Makrolon® DQ5122 polycarbonate improved lumen output by up to 6 percent compared to standard diffusion products at the same ability to diffuse light. For Trevos customers, this translates into improved comfort in industrial environments along with reduced energy bills—all without sacrificing light output. Optical simulations were used extensively during development of the Makrolon® DQ product line, identifying new material compositions that push this diffusion product toward the optical limit.
